    Notes: Abstract. Rural agricultural areas in southern Ontario, Canada, with potential for aggregate extraction have become a focus of conflict over proposed land use change. Geophysical and soil physical field measurements were used to map soil variation for quantitative land evaluation at the farm level. Apparent electrical conductivity of terrain was shown to be strongly correlated with depth to the groundwater table on two separate test sites. A digital terrain model was used to create thematic maps of the predicted pre-growing season soil water regime by contouring irregularly spaced electromagnetic survey and soil inspection points. Overlay analysis with a geographical information system (GIS) was used to produce an agricultural soil capability map for crop production. Adoption of a larger map scale provided significant refinement in detail over the published Canada Land Inventory soil capability ratings for agriculture, but both showed that Class 2 soils are dominant. The approach can improve the reproducibility of land capability assessments.

    HETEROLOGOUS TUMOUR GROWTH PATTERNS INDUCED IN RELATED MHC - DEFINED CHICKEN LINES BY SEPARATE ISOLATES OF AN AVIAN SARCOMA VIRUS STRAIN (1981)

    Notes: Different patterns of tumour growth resulted from inoculation of separate isolates of the Subgroup C Bratislava 77 strain (B77) of Avian Sarcoma Virus (ASV) into three closely-related inbred lines of chickens. The major genetic difference between these chicken lines is that each is homozygous for a different MHC haplotype. Since for one of the viral isolates, resistance to progressive tumour growth has been shown to be controlled by MHC-linked genes, the data presented here suggest that MHC-controlled tumour rejection operates on viral or cellular determinants different from those which define classical viral group or subgroup specificity.

    EFFECT OF EXTENDING BEEF PATTIES WITH MILK CO-PRECIPITATES (1978)

    Notes: Granulated type calcium co-precipitates (CCP) with and without wheat flour were used to extend ground beef with fat levels of 20 and 30%. The hydrated CCP was added at the level of 30% by weight and the physical, chemical and sensory properties of the mixture were evaluated along with those of all-meat patties and patties extended with texturized soya protein. Results of physical and chemical analyses were variable and showed no definite trend. All-meat patties gave the highest yield, lowest shrinkage and highest fat content after cooking. Patties extended with CCP and wheat flour had the highest moisture content and lowest penetrometer values at both fat levels. Sensory evaluation revealed that patties extended with CCP and wheat flour had the best appearance, flavor and texture and were generally the most acceptable.

    MHC GENE CONTROL OF GROWTH OF AVIAN SARCOMA VIRUS-INDUCED TUMOURS IN CHICKENS: A STUDY ON THE ROLE OF VIRUS STRAIN (1981)

    Notes: A comparison was made of growth patterns (progression/regression) of tumours induced by different strains of avian sarcoma virus in two partially congenic inbred lines of chickens homozygous for different MHC haplotypes. In each instance studied, the ability to regress tumours was shown to be a dominant trait controlled by MHC-linked genes. The results also demonstrate a difference in growth pattern between tumours induced by different strains of virus in an inbred line as well as different growth patterns of tumours induced by the same strain of virus in the two inbred lines. We conclude that the MHC-linked resistance gene is part of a polymorphic genetic region and, in addition, that there is immunogenic heterogeneity of the viral gene product expressed on tumour cells induced by closely related viral strains which is relevant to tumour regression. We suggest that the product of the src gene, p60src, is a plausible candidate for the immunogenic target of the MHC-linked rejection response.

    COMPLEMENTING MHC- AND NON-MHC-LINKED GENES AND RESISTANCE TO AVIAN SARCOMA VIRUS-INDUCED TUMOURS IN INBRED LINES OF CHICKENS (1981)

    Notes: Schmidt-Ruppin Rous sarcoma virus, subgroup B (SR-RSV-B), was inoculated into the wingwebs of chickens from three partially congenic inbred lines, G-B1, G-B2 and G-B3, homozygous for different MHC (B region) haplotypes (genotypes =B1/B1, B2/B2 and B3/B3 respectively). All birds developed tumours but only the G-B2 line resisted progressive tumour growth. Birds from lines G-B1 and G-B3 approached 100% susceptibility to progressive tumour growth, whereas most (G-B1 x G-B3) F1 hybrids were resistant to tumours induced by SR-RSV-B. The association of the resistance trait in F1 hybrids with genes of the B region was investigated by testing progeny of (G-B1 x G-B3) x G-B1 F1 and (G-B1 x G-B2) x G-B3 F1 backcross matings. Approximately 27% of the backcross population was resistant to SR-RSV-B-induced tumours and these resistant offspring were predominantly of the B1/B3 phenotype.We interpret these results to mean that resistance to progressive tumour growth involves complementation between genes (allelic or at separate loci) linked to or within the B region and that resistance is effective only when the complementing B region genes act in concert with complementing genes which assort independently of the MHC. We suggest that complementing B region-linked genes are homologues of complementing murine H-2-linked Ir genes. The function of the B region in determining growth of sarcomas may therefore be analogous to that of Ir genes.
